Patent CA-2064685-A1 (CA)
Inventor: OVODOV SERGEI J
IPC: C07K14/585
Filed: 1990-06-05
Abstract: Polypeptides are prepared in a cell-free translation system on ribosomes, where the system contains template RNA, ATP, GTP and amino acids as substrates, with the formation of translation products including the end polypeptide, AMP, GDP, pyrophosphate and inorganic phosphate, which are removed from the translation system while substrates are being spent, and ATP, GTP and amino acids are simultaneously introduced into the system to maintain their initial concentrations.  During the translation process, a translation system on ribosomes is used which includes template RNA and substrates in the form of ATP, GTP and amino acids, immobilized on microcapsules whose envelope represents polyelectrolyte complexes.
Patent CA-2069556-A1 (CA)
Inventor: SPENCE CLYDE L
IPC: B25B21/00
Filed: 1992-05-26
Abstract: ABSTRACT    An armrest attachable to a tool to provide support for a worker's wrist while the tool is being  manipulated  or  actuated.    The  armrest underlies the worker's forearm so the weight of the tool is borne partly by the worker's fingers and hand and partly by the worker's forearm.  Stress on the wrist is minimized and good wrist posture is maintained.   Due to the location of the armrest, the worker's forearm is located directly behind the tool handle where it can absorb kickback forces that occur as an incidental part of a lockbolt installation process.

IPC: B21B17/04
Filed: 1992-06-17
Abstract: A mandrel mill for rolling a tubing in a pass between a mandrel bar and a plurality of serially arranged roll stands.   Each roll stand has a plurality of pairs of grooved rolls whose grooves are paired to define a part of the pass.   The grooves of the rolls of a first roll stand define a hole having a circumference of not more than 1.12 times the outer circumference of a tubing at the exit of the final roll stand.   The grooves of the second-stand rolls define a hole having a circumference of not more than 1.06 times that outer circumference,  and those of the third-stand rolls define a hole having a circumference of not more than 1.02 times that outer circumference.  Thus, the mandrel mill is capable of preventing stripping miss even when the billet is of a high-alloy steel.

Title: Apparatus for re-using wires used once for mash seam welding
Inventor: NAKATSU MINORU
IPC: B23K11/30
Filed: 1992-06-25
Abstract: ?stract The present invention relates to an apparatus for re-using copper wire which was once used for mash seam welding in a mash seam welder for welding a lap formed by overlapping opposite side edges of a metal sheet between upper and lower roller electrodes via copper wires.  The apparatus is provided in a portion of the mash seam welder for taking up the copper wire having been used once for welding.  This wire is known as taken-up wire.   The apparatus feeds this taken-up wire as rewound wire to the mash welder to be used once again for welding.   The apparatus is comprised of a wire shape detection unit which is provided between a taken-up wire feed roller for feeding the taken-up wire and a taken-up wire take-up drum for taking up the taken-up wire fed from the feed roller.  The wire shape detection unit detects the shape of the rewound wire and provides a command to stop the feed of the metal sheet from the mash seam welder upon the detection of a defect in the wire shape.  A wire braking unit is provided between the wire shape detection unit and a delivery roller for delivering the rewound wire to the welder.  The wire braking unit includes a clutch unit for providing a brake force to the rewound wire in the direction opposite to the running direction and is capable of rotation only in the direction of feed of the rewound wire.

IPC: H01F27/24
Filed: 1993-03-23
Abstract: Abstract of the Disclosure A magnetic core, for use in fluxgate magnetometers or gradiometers, for example, comprises a pair of coaxial coils constituted by strips of permeable mag-netic material oppositely wound on a non-magnetic cylindrical tube.  At each of their opposite ends, the coils terminate in planes perpendicular to the length of the tube.  In the manufacture of a core, the strips at each end of the coils may be joined to each other to form a lap extending along the length of the tube.  In one embodiment, strip portions extending beyond the respective planes, including a portion of each lap, are cut off and removed.  In another embodiment, the entire lap at each end is removed after the strips at each end are welded to each other.  By virtue of the core con-struction, the signal-to-noise ratio of saturable core measuring devices using the cores is substantially improved.

Title: Lewis acid promoted transition alumina catalysts and isoparaffin alkylation processes using those catalysts
Inventor: COOPER MICHAEL D
IPC: C07C2/58
Filed: 1991-09-25
Abstract: This invention is to: a) a catalyst system, b) a component of that system comprising certain transition aluminas promoted with a Lewis acid (preferably BF3), and c) a catalytic process for the alkylation of isoparaffin with olefins. The catalyst component is produced by contacting the transition alumina with the Lewis acid at relatively low temperatures or at those temperatures at which certain characteristic peaks appear in the component's nuclear magnetic resonance (NMR) spectrum. The catalyst system comprises that component and an additional amount of free Lewis acid. The process entails olefin/isoparaffin alkylation using the catalyst component and its allied catalyst system.

Title: Atmospheric pressure calibration systems and methods
Inventor: ASHLEY ALLAN
IPC: G01C5/00
Filed: 1993-04-16
Abstract: ABSTRACT      Systems are provided to derive a value of barometric pressure at a defined location in the atmosphere at a computed geometric height.  By using the geometric height in a look-up table of pressure/height values representing a standard atmospheric profile, atmospheric deviation data indicative of the difference between measured and reference pressures at that atmospheric location (C) is derived.          Ground-based interrogators (10,20) located at spaced positions are used to initiate response signals from airborne transponders commonly installed in transient aircraft (C).          Using resulting range data based on round-trip timing differences in signals sent to (12,16) and received from (16,14) the airborne transponder (C), geometric analysis and computation is used (18) to determine the geometric height of the transponder representing a specific atmospheric location.          The height, together with barometric pressure data transmitted by the airborne transponder, are used (28) for the look-up of reference pressure data and derivation of atmospheric deviation data for that atmospheric location.          Systems and methods provide such data for inflight altimeter calibration, height determination, atmospheric pressure profile development, weather forecasting, transponder calibration and other purposes.

Title: Multi pin rotor fiber fluff generator
Inventor: BOWNS MRK W
IPC: D21B1/06
Filed: 1991-10-28
Abstract: A fiber fluff generator includes a housing having three substantially cylindrical portions, each of which mounts and contains a rotor having a rotor shaft and a plurality of rotor pins extending radially therefrom. The rotor pins are arranged in rows spaced incrementally along the length of the shaft with gaps therebetween, each row including plural rotor pins arranged in spoke-like fashion. The rotor shafts preferably are mounted parallel to one another and lie in a common vertical plane. The rotor pins on one rotor shaft are axially offset from and overlap with the rotor pins on the adjacent rotor shaft(s) so that the rotor pins collectively are interleaved to provide a cross-combing effect. Stator pins fastened to the housing extend radially inwardly into the gaps between the rows of rotor pins to provide further cross-combing interaction. As the rotors rotate, fiber introduced into an inlet at the top of the housing flows downwardly toward an outlet located at the bottom of the housing while it is fluffed and combed by the three-state rotor arrangement.
